General description

Whatman Polycap HD capsule filters are heavy duty polypropylene filters, commonly used in processing applications for general sample preparation; fine filtration; and refiltration for reverse osmosis, ultrafiltration and microfiltration membranes.

Heavy duty polypropylene filter capsule for chemical processing

Whatman Polycap HD capsule filters are used in processing applications to filter buffers, solvents, reagents and emulsions across a wide range of industries including clean air and gas equipment, cosmetics and personal care, food and beverage, inks and pigments, pharmaceuticals, photography, semiconductors and magnetic media.

Chemical processing applications often require a capsule filter to ensure a finishing step that yields a high purity final product. Different solution temperatures and pH values can complicate filtration. Whatman Polycap HD capsule filters are manufactured with polypropylene filter media, support system and housing allow use with a broad range of solutions, pH, and temperatures. Sturdy construction enables high flow rate and high retention capacity for excellent filtrate purity.
